I rarely recall my dreams but I do recall one nightmare with a meltdown.
After spending some time on a beautiful river. It ran through a forest and the sunlight was golden, like it was dawn or dusk. I could hear the water run and the birds sing. I loved it.
Then, I rounded a bend and it vanished. Instead I found myself in a windowless office space, lit by those florescent lights and filled with cubicles separated by those awful dividers. Phones rang and fingers clicked loudly across keyboards. Some one came up and welcomed me, telling me I'd be working here for the rest of my life.
I dreamed I ran into a corner near a window which was now there, curled up in it and started rocking, crying and screaming. I would try to hit anyone who came close. I couldn't think right, I was too terrified. It was worse than any meltdown that I can recall having in my waking hours.
I'm honestly surprised that I didn't scream aloud and wake the whole house up. I was so happy when I woke up and found that I was in my bed at home and it had all been a bad dream.
